An air strike killed at least 15 people and wounded 30 at a camp for displaced people in northwest Yemen on Monday, the humanitarian agency Doctors without Borders said.
Fifteen bodies and 30 wounded were taken to Haradh Hospital, where MSF operates, near the Al-Mazrak camp in Hajja province, said the manager of the MSF programme in the Middle East, Pablo Marco.
"It was an air strike," he said.
